Can we go Mustang Hunting now? K24A2/K24A1 Hybrid Civic

Budget EG TSX Head Swap Returns to the Dyno: Win?
By Aaron Gaghagen and Brian Gillespie
Budget EG stomped Aaron's B18C powered EG and that was solid. But when Budget EG hit the track against muscle and sports cars, it wasn't enough. We could keep up in the corners, not coming out of the corners though. First we tried to swap a TSX K24A2 head on to our Accord K24A4 block and that was a no-go. The shape of the combustion chamber didn't play well with our pistons. So we pulled a K24A1 from a wrecked CRV in the yard. The K24A2/K24A1 combo should give us the boost in power that we're looking for.

Back in the 90s when Honda made square engine bays which can fit j32 v6 with some modifications. Now the engine bays are pretty much all triangular-trapezoidal, from the mid 2000s. Good video Vtecacademy!

[@VTECAcademy]

We can fit a J in some of our newer Hondas. In fact... That may be on the horizon. Eventually!

What head gasket did you used for this combo an did you install the coolant diverter/partition plate ?

So did you ever make goal power with this setup ? Im doing the same setup exept no cat, 7.5 lb flywhee,l 70mm throttle body ,4.1 mega phone header,on k pro going to get jason waters to tune it on dec 4

[@findtherightbeat]

I'd suggest running 50 deg VTC gear + PLM Hytech style header + loong 3in intake and a good tune even with TSX cams will net good power

[@VTECAcademy]

We have the 50 degree VTC, but the header, exhaust and cams will get us there.

[@findtherightbeat]

@@VTECAcademy Maybe cast PRC pistons will also be ok for the budget theme to bump up the compression a bit

[@bobbydelamar606]

@@VTECAcademy Would a 40 deg. VTC be just as good and safer from hitting the valves? Curious cause im trying to make my CRX K24 safer for revving. (Type S oil pump, oil cooler,etc)

[@TheMrmagic101]

With this k24a1 block with a k24a2 head or even a k20a2 head do you not need to change or upgrade your pistons and rods? From my research only the k24a2 and jdm k24a 3 lobe vtec comes already equipped with better pistons and rods allowing for any 3 lobe vtec head to be added on with out rebuilding at least the rods and pistons

[@hondaowner2995]

my K24A1 needed RDX410's. PRC intake manifold 70mm tb, DC sports long tube and a 2.5 straight pipe. K20Z1 cams and it made 224/191 on 91 pump

VTEC Killer?

[@paul06660]

If you were running kpro beforehand and have ktuner now, you need to change the o2 sensor to match the ecu. The rsx-s 02-04 and 05-06 ecus have different primary o2 a/f sensors.

[@dstorm19]

This car has been on KTuner since first swap, He should also be running the TSX swap tune in the RSX Type S Tune selection.

[@VTECAcademy]

What he said.

[@TheMrmagic101]

Were you guys ever actually able to run the car with the stock 05 accord ECU

[@ericslimp2726]

I was thinking about doing this swap in a DC Integra would it be reliable for daily or a road trip from Missouri to New York 😂

[@athiam152]

Hi Brian, thanks for the informative video you that you shared with us. On the side note, from 24:46 - 24:50 are those still considered as safe AFR (13 to 13.5) from 6,000 to 7,300 rpm?

[@Pynoxim1]

For an N/A stock'ish K24 it's pretty decent. I personally run mine at 13.6'ish and it's all good.

[@VTECAcademy]

Although 14.7 is ideal for emissions, between 12 and 14 to 1 is better for power production. And that is a richer mixture.

[@athiam152]

@@VTECAcademy in other words, AFR 14 is still safe for WOT?

[@JerkingwithJesus]

on my 1998 honda crv i had unplugged my tps sensor and forgot to plug it back in. week later i go to drive it and i see the code and assume i just need a new map sensor. ended up driving a couple day like that before i realized it was unplugged. for b series engines they really dont need it but dont run good as the car is basically being almost flooded with fuel.

[@VTECAcademy]

That code adds a lot of fuel to keep the engine safe.

[@lindsaymccullock1176]

If the head is the clearance issue could you just use the 3 lobe cams and rockers my k24a4 head is factory machined with the idler spring sockets for the 3 lobe. Would this work?

[@VTECAcademy]

Maybe, but I haven't tried that.

[@mariopic]

ktuner uses 05 06 rsx style ecu this is hall effect vss u need to swap the case for a case that has vss in front of trans not in rear if u use kpro with 02-04 ecu should work fine also if u decap the 270cc accord injecters u get 440cc good cheap mod

[@VTECAcademy]

The KTuner can use both VSS for CSS.

[@professorlife1619]

Why not run 3in exhaust from the start? K’s I know love 3 inches 😅

[@tunanocrustgarage]

[@seancostello387]

What was loose? My new swap (still in shakedown phase) makes that noise of a dragging rotor when I power down the engine. Heard the exact same noise early in the video when you turned the engine off but not later in the video so I assume it got resolved.

[@seancostello387]

Sound at 13:17 is almost exactly what my car makes.

[@seancostello387]

No codes. Engine seems to run fine otherwise. Brand new timing chain and guides, etc

[@VTECAcademy]

The noise I hear is the intake air tube sucking as the engine quits but is winding down.

[@zacharycofer5929]

Tps an map sensor plugs swapped will cause it to not rev also, I made that mistake before lol

What serpentine belt are you using? I just swapped a k20a2 for a k24a2. No ps or ac. I have an ep3 pulley and I switched the water pump housing to use the oil cooler. Now the k20 belt doesn’t fit.

[@paul06660]

you need to run the crankshaft pulley from your k20a2. Possibly the belt tensioner too. Im running the same setup k24a2 with k20a2 crank pulley, oil cooler, water pump and housing with rsx power steering pump, alternator and tensioner, 7 rib belt part number 537k7. No ac compressor and it fits and tensions perfectly. hope this helps.

How did you damage the original ecu? Hoping to avoid that

[@ceeelowe]

Their capacitors wear out if you’re always plunging in and running scan tools and tuners constantly, I’ve fried two because I left my scan tools plugged in overnight. Ruined a new battery too somehow. I only plug in to scan a code or run a diagnostic now. But I use to do it all the time just to watch the live data… but old ECUs/PCM can’t handle it for long. Luckily ECUs at the junk yard are $40 instead of $1800 new from Honda

[@greeenteeee]

@@ceeelowe wait. I run a ScanGauge II for live data. And for years people have used BT OBDII readers. Are you saying I’m running the risk of damaging the ECU? It’s not luckily because some ECUs are getting hard to find.

[@ceeelowe]

@@greeenteeee you’re most likely ok I believe I have a phantom electrical short in my battery harness. I have a Bluetooth code reader for JDM cars only. Once i started plugging it in and overzealously scanning literally all the time because I just got it and love it so much I somehow fried my computer…twice. Lol. Later I saw from @Speed Academy that they had similarly run into problems with wore out capacitors in old ECUs, since Bluetooth live data was the only thing that had changed for me I gotta blame it on my daily live data scanning was just too much for the ol car brain. 2007 L15 GD3 Again I left the bluetooth dongle plugged in overnight… multiple times… and which is what mostly fried the ECUs. Got me gun shy to scan my newest junkyard ECU now 😂

[@greeenteeee]

@@ceeelowe so you blame an OBDII reader (which is what my ScanGauge II essentially is- I’ve left it connected overnight all the time, rotate it between 3 vehicles) but then you’re saying I’m okay w the ScanGauge and because you have an electrical gremlin? I don’t follow the contradiction. I leave it plugged in to monitor things like coolant temp, batt voltage, and whatever else need be, on the fly- never heard of capacitors being blown out until you, so I’m looking for clarification

[@ceeelowe]

@@greeenteeee I’ve never had an ECU go bad until I got a Bluetooth scan tool… if you’ve never had an issue, then that’s why I say your fine and it must be an electrical arc shorting somewhere in my specific car’s system; but I’ve also heard from a couple KZbin mechanics that running scanners all the time just overall isnt good for an old ECU…. so I’m not trying to confuse u just wanted to share my experience, getting towed, and walking home 8 miles from a Honda dealership at noon ☀️🌞☀️ is an experience I dont wish upon my worst enemy so just FYA, entropy and Murphy’s law do apply to old fickle ECUs but luckily theyre still fairly cheap at ebay junk yards if u do fry it. So scan away and read that sweet live data all day everyday my brotha 😎
